Claims
- 1. A vaso-occlusive device comprising:
- i. an outer helically wound primary coil having a first end and a second end, an axis between said first and second ends, and having a lumen between said first end and second end, and
- ii. a stretch-resisting member extending through at least a portion of said lumen and fixedly attached to said primary coil in at least two axially separated locations.
- 2. A vaso-occlusive device comprising:
- i. an outer helically wound primary coil having a first end and a second end, an axis between said first and second ends, and having a lumen between said first end and second end,
- ii. a polymeric stretch-resisting member extending through at least a portion of said lumen and fixedly attached to said primary coil in at least two axially separated locations; and
- iii. a deployment tip attached to at least one of said first end or said second end, said deployment tip comprising an electrolytically detachable end adapted to detach from a pusher by imposition of a current upon said pusher, and wherein the polymeric stretch-resisting member allows for repositioning of the vaso-occlusive device after deployment.
- 3. The device of claim 2 where the device has a secondary form.
- 4. The device of claim 3 wherein said secondary form is C-shaped, clover-leaf shaped or double-looped shape.
- 5. The device of claim 2 additionally comprising external filamentary material attached to said primary coil.
- 6. The device of claim 5 wherein the external filamentary material comprises a looped fibrous elements or a fibrous woven or braided tubular member.
- 7. The device of claim 2 wherein the stretch-resisting member comprises a ribbon.
- 8. The device of claim 7 wherein said secondary form is C-shaped, clover-leaf shaped or double-looped shape.
